 The stop command is always **graceful by default**:
-1. Sends exit keys to the agent TUI (`/exit` for Claude, `Exit` for Agy) and waits 3 seconds.
+1. Sends exit keys to the agent TUI (`/exit` for Claude, `/exit` for Agy) and waits 3 seconds.
 2. If still alive, issues `herdr kill-session` (SIGTERM) and waits 5 seconds.
 3. If still alive, kills the pane PID via SIGKILL (`kill -9`) as a last resort.
 4. Auto-captures the conversation ID into the row (`claude_session_id_own`/`agy_conversation_id_own`) before killing, ensuring the next resume uses a race-free tier-1 lookup.
